I'm looking for a way to get galvanic isolation of a USB device (whatever it is). Do you know somewhere a company or a product or a way to get this isolation, I think that optocoplers won't fit the bandwidth.
I need such product for USB high speed or at least USB full speed.

Please don't top post. Thank you.
Do you realize that anything that is USB 1.1 conforming and works at full speed? A USB 1.1 hub will work with USB 2.0 host and device at full speed, just not high speed.
It is a common misconception to think that saying USB 2.0 is the same as saying USB High Speed. It may be true that USB 1.0 and 1.1 did not have High Speed and that USB 2.0 does have high speed, but USB 2.0 also has Low Speed and Full Speed. So saying USB 2.0 says nothing about the speed.
If you need High Speed, you should say USB High Speed. It is the USB
2.0 that is then implied, not the other way around.
Who says we are here to help? Our purpose is to carp and fuss about foolish misuse of usenet, such as failure to snip (horrible example above) and lack of precision. The sacrifice of at least one rooster on the block is necessary before any help can be offered. Better results are had with sheep, and even better a bull. Without us all is chaos.

Appologies for the "lack of precision" with my cut paste in the .sig ... that was ugly.
